MECHANICAL RAZOR.

Specification of Letters Patent. I

Patented Dec. 3, 1918.

Application filed March 2, 191?.1 Serial No. 151,899. j I

To all whom, it may concern:

Be it known that I, J OHN W. HALTERMAN, United States, residing atWillows, in the county v California, have invented certain new anduseful Improvements in Mechanical Razors; and I do declare thefollo'wingto be a full, clear, and exact description of the same,reference being had to the accompany ng drawings, and to the charactersof reference marked thereon, which form a part of this application. v

This invention relates to improvements in mechanical razors designed foruse 'in'shaving the hairs of the face by mechanical means rather thanthe now commonly used of various types.

- heretofore been invented and I am somewhat familiar with the prior artand the aim of my present invention is to overcome some of the outsideof the casing. Such a structure as this is rougher on the face and ridessome of the hairs down while passing over the face movable as a unitwith such cutter.

instead of cutting them. Also the guard on the outside is a hindrance toclose shaving. I have therefore devised a meansor structure whereby theguards are placed within the casing and operable preferably with or as apart of the movable blade. This movement will be either rotary oroscillating and in the present disclosed type, which is the one I givepreference to at this time, I have shown an oscillating cutter with theguards connected therewith inside of the casing and I have furtherprovided a specially designedmechanism for operating such oscillatingcutter.

A still further object of the invention is gu -to provide an easilyremovable supporting for the cutter so that the same can be readilytaken apart for the purpose of;

e handle member is also connected'onto the razor handle cleaning therazor and this removab casing in such a manner as to maintain the samerelative position with respect to the oscillating cutter for a purposeas will pres ently appear.

deficiencies disclosed by such prior art and one of the most .importantof these i A further obj ect of the invention is to pro- I duce a'simple and, inexpensive device and yet one which will. be exceedinglyeffective 'such structure and relative arrangement of parts as willfully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate correspondingparts in the Figure 1 is aperspective view 'of thecomplete device. 1Fig. 2 is a vertical transversefsection through the center of the razor.

Fig. 3 is-a vertical longitudinal section Fig. 4: is an end-view oftherazor casing showing the handle removed. v

Fig. 5 is the bottom plan view of the razor casin Referring now moreparticularly to the characters of reference 'on the drawings, I

first provide a razor casing 1 which is substantially cylindrical incross section and provide it for a portion of its; length with a smalllongitudinal slot 2, the edges of'such slot being sharpened down to arycutting blades. 4 V .1

p In each end of the casing 1, I provide an adjustable bearing'member 3substantially as shown in my pending application for patent filedNovember 2nd, 1916,; Serial Number-129,105. I

Journaled inthe bearing members 3, I provide a shaft 4:.

form stationr "as Secured to or formed a component part of this shaft 4are a plurality of spaced segmental guard members -5 projecting to apoint closely adjacent the slot 2 and arranged to oscillateback andforth across said slot with a rocking motion of the shaft 4r impartedthereto in a manner as will presently appear. A small'cutter bar 6 isrigidly set into the outer edge of the guards 5 or formed as a componentpart of said ards. This bar 5 has a slight angling position with respecttothe cutting edges of the slot 2. In practice'the lower edge of the bar6 projects below the lower edges of I the guards 5 a distance equal tothe approximate diameter of a hair.

I Fixed centrally of the length of the shaft 4'is an upwardly projectingarm 7 its upper end being bifurcated as at 8 to receive a small drivingwheel This driving wheel I Y 8. The necessity of this will be clearlyap- 9 is secured in an eccentric manner to the "driving shaft 10suitably journaled in side walls-of the spring clip member 11. The

sides of the member 11 are slightly resilient and provided with slots 12adapted to fit over the side set screw 13 of bearing members 3. By meansof this structure the osi- 3 may be adjusted to different positions andtion of the member 11 relative to the s aft 4, is always the same so asto make positive the connection 'betweenthe members 9 and parent sinceit will be noted that the bars 3 if the member 11 in'which the shaft 10is journaled, isnot relatively adjusted, the connection between themembers 8 and '9 might become too loose or too-tight as the case mightbe. On the member 11 is fixed the handle member 14 within which is aflexible cable suitably connected to the'driving shaft 10. The cable 15may be driven by any motive meansfound desirable.

When motion is imparted to the shaft 10, the rotation of such shaftrotates'the driving wheel 9 with an eccentric motion which imparts tothemember 7 an oscillating motion. This inturn imparts to the shaft 4,guards 5 andcutter bar 6 a similar oscillating motion. With this actionthe bar 6 moves back and forth across the slot 2. The

,' casing 1 being placed against the face causes the hairs on the faceto project into the slot 2 where they are engaged by the bars 6 and thatthe bar 6 projects below the guards is carried into contact with thecutting edge along the slot 2 where they are cut off with a shearingaction due to-the fact that the bar 6 is slightlyangled with respect tothe cut J ting edge as previously described. The

guard-s 5 hold the skin and flesh of the face from being rolled inbetween the cutter bar and the cutter edge. The small distance notenough to allow of the flesh or the skin being rolled between such barand the cut ting edge but at the same time it allows of a continuouscutting surface uninterrupted by the/guards. If the guards cameimmediately adjacent the cutting edgeit might be possible that a hairwould get caught between the guard and the cutting edge with theresultthat it would be pulled instead of out. It is for this reason that thebar 6 projects below the guards 5 a distance equal to the diameter of ahair so that all the hairs which are drawn into the casing will besheared off with no possible chance of them being caught and pulled.

While of course it would be possible'to construct the cutter bar 6 sothat it would perform a complete rotary motion instead of an oscillatingmot-ion, still I believe the rality of guards fixed to the sha aasaeoeoscillating motion to be preferable for the reason that the hairs areout against either edge of the slot 2. Thus no matter which way thehairs on the face lie, they will .be picked u and cut whereas if thecutter rotated 0111 the razor would have to be positioned so as to workagainst the hairs in order to be efficient in its action. By theconstruction here shown however the will be quickly cut off irrespectiveof w ich Way they lie since if the cutter rides over them when movin inone direction it will pick them up anfcut them off when moving in thereverse direction.

The top of the casing 1 is provided with.

a free open portion 1 so as to allow of a'free movement of the wheel 9and also to allow of the razor being readily cleaned when the springclip member 11 is removed from the screws 13.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfils the object of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device,-still in practice such deviations from suchdetailmay be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended 3 claims Having thus describedmy invention I i I clalm as new and'useful and desire to secure byLetters Patent is:

1. A mechanical razor comprising a casing provided with a'slot havingits edges formed into cutting blades, a longitudinal driven shaftjournaled in the casin a plu- I transversel of the slot area, a cuttingblade set into the guards and coacting with the cutting blades andprojecting beyond the outer edge of the guards for a distancesubstantially equal to the diameter of a hair whereby -a continuouscutting area will be pro-' v1ded along the-entire length of the cuttingblades to prevent any hair being cau ht and -1ng an oscillating movementtransversely across the slot area, and a cutter bar carried by theguards and coacting with said blades.

In testimony whereof I affix my signature.

JOHN W. HALTERMAN.
